How does Motherwort work?

Motherwort might slow down the heart and thin the blood. It might also stimulate uterine tone and blood flow.

Are there safety concerns?

Motherwort is POSSIBLY SAFE for most people when taken by mouth appropriately. Side effects include diarrhea, stomach irritation, uterine bleeding, sleepiness, and allergic reactions. Contact with the skin can cause rashes and increased sensitivity to the sun.

Special Precautions & Warnings:

Pregnancy and breast-feeding: Taking motherwort by mouth during pregnancy is LIKELY UNSAFE and should be avoided. Motherwort can stimulate the uterus and might cause a miscarriage.

There is not enough reliable information about the safety of taking motherwort if you are breast-feeding. Stay on the safe side and avoid use.

Heart conditions: Motherwort can interfere with the treatment of heart conditions. If you have a heart condition, get your healthcare provider's advice before starting motherwort.

Surgery: Motherwort can slow down (sedate) the central nervous system (CNS). There is a concern that when combined with anesthesia and other medications used during and after surgery, motherwort might cause too much sedation. Stop using motherwort at least 2 weeks before a scheduled surgery.

Uterine bleeding: Motherwort may be able to stimulate uterine blood flow, which is why some women try it for starting their periods. If you have a uterine bleeding condition, use motherwort with caution, since it might make this condition worse.
